IMPROVEMENT IN THE CONSTRUCTION OF THE AFTER HULLS 0F YACHTSI &c-

Specification forming part of Letters Patent No. 152,805, dated July 7, 1874; application filed l April 25, 1874.

To all whom it may concern:

Be it known that I, EMrsoN EDWARD MID- DLETON, of Southampton, in the county of Hampshire, in England, have invented a new and useful improvement in building and altering, by lengthening by the stern, the after hull of yachts and other vessels, of which the following is a specification:

The figure is a view illustrating my improved method of building and altering the after hull of vessels.

My invention has for its object to increase the capacity of vessels for carrying cargo or ballast, to enable them to carry more canvas to improve their sailing qualities, and to make them safer in rough Weather and in heavy gales of wind. The invention consists in the arrangement of the stern-post of yachts and other vessels with its lower end inclined to the rearward at an angle of forty-five (45) de grees, more or less, in connection with a corresponding rearward extension of the keel, as hereinafter fully described.

AB represent the deck-line. O D represent the ordinary position of the sternpost.

as that of the old pattern stern-post, and as shown in the figure, the stern-post having now the position 0 D. The keel E F is then lengthened to the position E F to meet the lower end of the stern-post G D. This enables the counter G to be extended to the rearward, giving a long and extremely useful counter, as shown in the figure, the counter being made at any desired slope to the stern-post (l D, at or near the water-line H H, as shown at I H in the figure. The rudder may be quadrilateral in form, and hung with the blade at right angles to the stern-post O D, the rudder-post being parallel to the same 0 D. The rudderblade should be set rather low on the rudderpost, so that the top corner of the blade may project a little above the water-line.

The rudder is not a part of the invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The arrangement of the stern-post of yachts and other vessels with its lower end inclined to the rearward at a suitable angle, from ten (10) to forty-five degrees, more or less, in con nection with a corresponding rearward extension of the keel, substantially as herein shown and described.

April 2, 1874.
